Abstract

The utility model relates to an electrical-molten plastic pipe fitting, particularly an electrical-molten plastic pipe fitting with automatic welding regulation. The utility model aims to only focus the effect of an electrical-molten welding process and synthesize various influencing factors so as to determine the stopping time of welding. The utility model has the technical project that a detecting hole 6 is arranged on the outer wall of the pipe wall 1 of the existing electrical-molten plastic pipe fitting, which is adjacent to a binding post 2 and the detecting hole 6 without penetrating through the pipe wall 1 is positioned on the inner side of the binding post. The utility model has the advantages that the utility model has an automatic welding process; the welding time is determined by the synthesized parameter of an operating site without being determined in advance; the utility model can avoid overlapped welding and effectively discover the condition that pipes are improperly embedded.

Description

Automatically regulate the welding electric melting plastic pipe

The utility model relates to a kind of electric melting plastic pipe, particularly a kind of automatic adjusting welding electric melting plastic pipe.

Existing electric melting plastic pipe, employing is established wiring terminal on the pipe fitting outer wall, establish the heating resistor coil between two wiring terminals, the heating resistor coil is embedded on the pipe fitting inner wall, and manual methods is imported weldingvoltage, weld interval, the ambient temperature correction value to weld interval to welding machine during welding.Also having a kind of method is the bar code input method, is to read the expressed information of bar code that sticks on the pipe fitting with the light pen on the electro-fusion welding machine, and welds according to corresponding setting rule.The third method is the resistance input method, adjusts the welding machine parameter according to the resistance that is serially connected in resistance on the coil.In the process of electric smelting welding, the factor that influences welding quality has: 1, the energy input deviation that causes of power supply fluctuation; 2, the mistake welding that causes of welding parameter input error; 3, the energy input deviation that causes of pipe fitting self-resistance deviation; 4, the influence of ambient temperature; 5, tubing embed improper, the external force interference that produces when mainly referring to the gap that embeds and two sections tubing disalignments.Above-mentioned which kind of welding method all can't provide a comprehensive controlled quentity controlled variable to a multi-variable system, especially can't revise to embed the influence of gap to welding quality, and this is a factor to welding quality influence maximum in fact.

The purpose of this utility model is only to pay close attention to the effect that electric fusion welding taps into journey, and comprehensive various influence factors are determined the termination time of welding, and a kind of automatic adjusting welding electric melting plastic pipe is provided.

The purpose of this utility model is realized by following technological scheme: a kind of automatic adjusting welding electric melting plastic pipe; it comprises tube wall 1; 2 wiring terminals 2 are established in tube wall 1 outside; be provided with protecting jacket 4 around the wiring terminal 2; be connected with heating resistor coil 3 between 2 wiring terminals 2, heating resistor coil 3 is embedded on the inwall of tube wall 1, it is characterized in that: tube wall 1 outer wall near wiring terminal 2 is provided with detection hole 6; detect hole 6 and do not penetrate tube wall 1, detect hole 6 in the wiring terminal inboard.

A protecting jacket 4 is provided with 2 spacing muscle 5.

Spacing muscle 5 is towards a side that detects hole 6.

The utility model has the advantages that: the welding sequence automation; Determine by the comprehensive parameters of operation site, need not to pre-determine weld interval; Can avoid overlapping welding; Can find effectively that tubing embeds situation improperly.

Below in conjunction with embodiment shown in the drawings the utility model is further described:

Fig. 1 is that a kind of embodiment's of the present utility model structure is partly cutd open schematic representation;

Fig. 2 is the plan view of Fig. 1.

As shown in Figure 1 and Figure 2, the applicant has implemented a kind of automatic adjusting welding electric melting plastic pipe, establish 2 wiring terminals 2 in tube wall 1 outside, around wiring terminal, be provided with between 4,2 wiring terminals 2 of maintainance set and be connected with heating resistor coil 3, heating resistor coil 3 is embedded on the inwall of tube wall 1, on outer wall, be provided with and detect hole 6, can not penetrate tube wall 1 near the tube wall 1 of wiring terminal 2, and in the wiring terminal inboard, be provided with 2 spacing muscle 5 on maintainance set 4, spacing muscle 5 is towards a side that detects hole 6.The effect of spacing muscle 5 is the positions that limit the power supply electric melting plastic pipe output plug of electro-fusion welding machine, and the detecting head on the plug just in time is inserted in the detection hole 6, also makes protecting jacket 4 firmer simultaneously.When welding, the 3 energising heating of heating resistor coil, the inwall of tube wall 1 is heated with the outer surface of pipe fittings that embeds, the molecular motion of plastics accelerates to make the pipe fitting of embedding to form one with tube wall 1, detect hole 6 this moment also can temperature distortion, the bottom of detecting hole 6 constantly upwards raises, the detecting head on the jack-up plug upwards, during to certain altitude, detecting head is given electrical signal of electro-fusion welding machine, expression welds this moment, and electro-fusion welding machine just can be stopped power supply behind the signal that is subjected to two detecting heads, and welding has also just been finished.No matter electric melting pipe fittings is much, the bore in detection hole, all constant with the distance of wiring terminal.When electric melting pipe fittings is bend pipe or threeway, when needing the welding respectively of a mouth of a mouth, can be set to a place to two wiring terminals side by side, each mouth is established a pairs of posts.
